700R4 Transmission

I have changed two Trans. on my 1988 G-20 Van after about three days they both have loose the drive. They only go into first and second gear. When they shift up any further motor just screams what could be wrong Trans Bad two in a row ?

Were the trannies used or rebuilt? Rebuilt by the same person?

Early (pre 1989) 700R4's have weak pumps and puke out easily.

Are you replacing the torque converter and flushing the lines and trans cooler also?If not you may have stored metal debris causing repeat failures.
